Many singers go off the radar for one reason or another. Sometimes, when they come back they look better (i.e. J-Lo, LL Cool J), and sometimes, they come back looking so as well (i.e. Whitney Houston, Britney Spears). Mariah Carey came book looking SMOKING, and she was eager to show it off, as demonstrated by her latest music videos.

Just as Ryan Reynolds revamped his body for 'Blade: Trinity', Jessica also whipped herself into shape for the role. Her physique (and attitude in the movie) was reminiscent of Sarah Conner in 'Terminator'. She's a lean, mean, fighting machine, but still feminine in appearance.

Sure, she yo-yo diets, and there's a lot of drama going on in her life that more often than not affects her physique, but when Ms. Spears is in shape... SHE IS IN SHAPE! Tight abs, toned legs, small derriere - there's nothing this girl is lacking.

At first, when she started out as a Fly girl on 'In Living Colour' and in her earlier career, everyone LOVED her booty. But then, when 'thin' was 'in', it became the 'butt of jokes' (pun intended). However, she has a trainer and her bum is half the size it was, despite having kids. She definitely now has an enviable body.

If I had to wear teeny tiny little skirts made by my mom in front of tens of thousands of people every time, I'd want to have tight legs and glutes too. Beyonce wears outfits that show off her curves and musculature quite well.
